To all: teh/0m it mai] vorwahl; I Be itknown that I,l ARGYLE CAMPBELL, t anois, have invented a certain new and useful, Improvement in Metallic Car-Roofs, of which My Invention re ates to metallic car-roofs. i The object of-my invention is '-td provide' niumamount rof strength',w

At intervals along the car I con- -irons 13, by means oi' the'angle-irons 1 5.and bolts' or rivets 16. Atv

of it from end 'to end I vlace a U-sha e ridge- 17 upon these carlines 14, the lottom of dfn'ectly upon the carlines and thereto vby any suitable means.-

Upon each of these 'anges 18 and its adjacent side of the 20, running from end to endof` the car, and, secure the sameby any suitable means to the*vf of thel car., Over the top edges of the sebiegtioa of x'.trsrats. Apputson met 'caoba saisies. serial No. sspsz;

Having thus described my invention, what 85 I claim. as new, and desire to secure by Let ters Patent, is- 1. In a metallic car, in combinationvwith the sides and ends ofthe car a plurality of carlines extendin the car from end to end, an to the roof- ?tsntd dass 2e, 190e.
